UPDATE
ISSUED AT 654 AM CDT FRI OCT 2 2026
THE FORECAST FOR TODAY REMAINS ON TRACK.
MINOR COASTAL INUNDATION, MAINLY IMPACTING COASTAL PORTIONS OF
MOBILE COUNTY, IS SLOWLY SUBSIDING AT THIS HOUR ON THE BACKSIDE
OF HIGH TIDE. ANOTHER ROUND OF COASTAL FLOODING IS EXPECTED BOTH
SATURDAY MORNING AND SUNDAY MORNING IN THE PRE-DAWN HOURS DUE TO A
COMBINATION OF SPRING TIDAL CYCLES AND INCREASING ONSHORE FLOW.
GUIDANCE OVERNIGHT INDICATES THAT THE RISK FOR COASTAL FLOODING
WILL LIKELY EXTEND ACROSS THE ENTIRE COASTLINE OVER THE WEEKEND.
RIP CURRENT PROBABILITIES INCREASED FOR THE SUNDAY NIGHT INTO
MONDAY TIMEFRAME, SO WE OPTED TO EXTEND THE HIGH RISK OF RIP
CURRENTS THROUGH MUCH OF THE DAY ON MONDAY. THE RISK SHOULD
STEADILY DROP THROUGH THE MORNING HOURS ON MONDAY. OVERNIGHT
GUIDANCE INDICATES THAT THERE IS AN INCREASING LIKELIHOOD OF A
HIGH RISK AGAIN BY LATE TUESDAY NIGHT THROUGH THE MIDDLE TO LATTER
PART OF THE WEEK. SURF HEIGHTS INCREASE AS WE ROLL INTO THE
MIDDLE TO LATTER PART OF NEXT WEEK AS WELL.
HIGH-RES GUIDANCE COMBINED WITH HREF PMMS HAVE STARTED TO TREND
SLIGHTLY HIGHER WITH THE POTENTIAL RAINFALL AMOUNTS, THUS GIVING
US INCREASING CONFIDENCE THAT THIS WEEKEND'S HEAVY RAINFALL WILL
LIKELY LEAD TO AT LEAST SOME FLASH FLOODING ISSUES ALONG THE
COAST. BUMPED UP THE RAINFALL TOTALS IN OUR MESSAGING TO 4-6
INCHES ACROSS MUCH OF THE AREA WITH A FEW LOCATIONS POTENTIALLY
RECEIVING UP TO 7-10 INCHES OF RAIN THROUGH MONDAY. 07/MB
DISCUSSION
ISSUED AT 158 AM CDT FRI OCT 2 2026
A WAVE OF DEEP TROPICAL MOISTURE MOVING INTO THE EASTERN GULF WILL
BEGIN TO ENTER THE AREA TODAY VIA SOUTHEAST FLOW AROUND A RIDGE OVER
THE WESTERN ATLANTIC. PWATS WILL RISE FROM AROUND 2 INCHES TO AROUND
2.3 INCHES THROUGH THE DAY, LEADING TO AN INCREASE IN SHOWER AND
STORM CHANCES. THE GREATEST COVERAGE WILL FOCUS OFFSHORE AND OVER
COASTAL COUNTIES DURING THE MORNING, EXPANDING INLAND FOR THE
AFTERNOON HOURS WITH POPS AS HIGH AS 60-80% SOUTH OF HIGHWAY 84.
LOCALIZED HEAVY DOWNPOURS ARE EXPECTED WITH THIS ACTIVITY AND A
MARGINAL (LEVEL 1 OF 4) FLASH FLOOD RISK HAS BEEN OUTLINED BY THE
WPC.
THE MAIN STORY THROUGH THE WEEKEND CONTINUES TO BE THE POTENTIAL FOR
MULTIPLE ROUNDS OF HEAVY RAINFALL AND FLASH FLOODING. AS THE WAVE OF
TROPICAL MOISTURE BEGINS TO CONVERGE ALONG THE NORTHERN GULF COAST
AHEAD OF A STALLED FRONT TO THE NORTHWEST, PWATS ARE FORECAST TO
SURGE TO AROUND 2.4-2.5 INCHES, PLACING THEM ABOVE THE 99TH
PERCENTILE FOR EARLY OCTOBER. LOW-LEVEL CONVERGENCE ALONG AND EAST
OF A BROAD SURFACE TROUGH WILL LEAD TO PERIODS OF WIDESPREAD SHOWERS
AND STORMS OVER MUCH OF THE AREA THROUGH THE WEEKEND. AS SOME
GUIDANCE IS HINTING, IT IS NOT OUT OF THE QUESTION FOR THE SURFACE
TROUGH TO CLOSE OFF INTO A WEAK LOW PRESSURE AREA OVER THE NORTHERN
GULF. THIS WOULD POTENTIALLY RESULT IN A PROLONGED PERIOD OF
WIDESPREAD HEAVY RAIN WITH EMBEDDED TRAINING CONVECTION OVER THE
AREA, PARTICULARLY SATURDAY NIGHT INTO SUNDAY. THE DEEPLY MOIST
ENVIRONMENT WILL SUPPORT HIGHLY EFFICIENT WARM-RAIN PROCESSES AND
LOCALLY INTENSE RAINFALL RATES. THE GREATEST CONCERN FOR REPEATED
ROUNDS OF HEAVY RAINFALL WILL BE NEAR THE COAST, THROUGH THE TIMING
AND DURATION OF INDIVIDUAL ROUNDS REMAINS UNCERTAIN.
TOTAL RAINFALL AMOUNTS THROUGH MONDAY MORNING REMAIN UNCERTAIN, BUT
THE CURRENT FORECAST REMAINS FOR GENERALLY 2-3 INCHES ACROSS THE
INTERIOR AND 3-6 INCHES ACROSS THE SOUTHERN HALF OF THE AREA, WITH
LOCALLY HIGHER AMOUNTS POSSIBLE. TOTALS OF 6-9 INCHES CANNOT BE
RULED OUT NEAR THE COAST WHERE TRAINING CONVECTION OCCURS. THE
POTENTIAL FOR FLASH FLOODING REMAINS A CONCERN, PARTICULARLY IN
URBAN AND POOR DRAINAGE LOCATIONS. SINCE OUR SOIL CAN GENERALLY TAKE
A LOT OF RAIN BEFORE FLOODING BEGINS GIVEN LACK OF RECENT RAINFALL,
WIDESPREAD FLOODING IS NOT CURRENTLY EXPECTED. THE WPC MAINTAINS A
SLIGHT RISK (LEVEL 2 OF 4) OF EXCESSIVE RAINFALL FOR THE SOUTHERN
HALF OF THE AREA ON SATURDAY AND THE ENTIRE AREA ON SUNDAY.
THE COLD FRONT IS CURRENTLY FORECAST TO SLOWLY CLEAR THE AREA AND
PUSH OFFSHORE EARLY NEXT WEEK, GRADUALLY FILTERING IN DRIER AIR AND
REDUCING RAIN CHANCES THROUGH MIDWEEK. BREEZY NORTHEAST FLOW AND
COOLER TEMPERATURES ARE EXPECTED BEHIND THE FRONT. UNCERTAINTY GROWS
SUBSTANTIALLY GOING INTO THE LATTER PORTION OF NEXT WEEK.
ALONG THE COAST, CONTINUED ONSHORE FLOW COMBINED WITH THE ONGOING
KING TIDE CYCLE THROUGH THE WEEKEND WILL LIKELY LEAD TO MINOR
COASTAL FLOODING DURING THE EARLY MORNING HIGH TIDES, WITH WATER
LEVELS REACHING UP TO AROUND 2 FEET ABOVE NORMALLY DRY GROUND. THE
GREATEST CONCERN FOR COASTAL FLOODING IS ALONG NORTHERN AND WESTERN
MOBILE BAY AND THE MISSISSIPPI SOUND EARLY THIS MORNING, AND
POSSIBLY EXPANDING TO INCLUDE ADDITIONAL PORTIONS OF THE COAST FOR
SATURDAY MORNING. IN ADDITION, A HIGH RISK OF LIFE-THREATENING RIP
CURRENTS CONTINUES AT ALL AREA BEACHES THROUGH SUNDAY, FOLLOWED BY A
MODERATE RISK EARLY NEXT WEEK. JGC/98
AVIATION
(12Z TAFS)
ISSUED AT 654 AM CDT FRI OCT 2 2026
VFR CONDITIONS PREVAIL OUTSIDE OF CONVECTION THROUGHOUT THE TAF
CYCLE. SHOWERS AND STORMS WILL CONTINUE TO DEVELOP NEAR THE
COASTLINE AND PUSH INLAND THROUGHOUT THE DAY. PROB30 GROUPS
CONTINUE FOR THE TERMINALS THROUGH EARLY EVENING GIVEN THE
POSSIBILITY OF BRIEF REDUCTIONS IN VISIBILITY AND CEILINGS DUE TO
PASSING SHOWERS. GUSTY CONDITIONS ARE POSSIBLE ALONG THE IMMEDIATE
COASTLINE THROUGHOUT THE DAY WITH GUSTS UP TO 20 KNOTS AT TIMES.
